Answer:
49,850.64
Step-by-step explanation:
To find the area of a circle, you must use the formula pi r ^2 (pi r squared).
In this case, we are using 3.14 for pi, so we can add that into the formula.
3.1r^2
We also know the radius, so we can add that in too.
3.14 x 126 ^2
Now solve.
126^2 = 15,876
15,876 x 3.14 = 49,850.64
49,850.64 is the answer.
Hope this helped!
P(A) = P(8) + P(9) + P(10) = 3/10 so P(A complement) = 1 - P(A) = 1 - 3/10 = 7/10 - D
equation for first figure=2x+y=2
equation for second figure= 4x-y=8
(use formula x/a+y/b=1)
where, a=x component and b= y component..
Answer:
m=-2
Step-by-step explanation:
As the product of the roots of a quadratic equation is c/a in ax^2+bx+c=0
here a=2, b=+8, c=-m^3
Given c/a=4
-m^3/2=4
-m^3=8
m^3= -8
m=-2.
